ENVELOPE.

Specification of Letters Patent: Patent-ed J 11119, 20, 1922.,

' m caw m December 13,1920. Serial no. 430,243.

To all whom it maytohcem:

- l 3e it known that I, YORKE Bnizonss, a

c1t1zen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and use- .ful Improvements in Envelopes, of which the following "is a specification.

This invention relates to improvements in envelopes, and has especial reference to double envelopes, adapted for carrying difl'erently classified mail matter in the respective separated pockets.

Business houses in mailing catalogs to prospective customers find it expedient, many times, to accompany the catalog with a personal letter. tions be mailed in a single sealed envelope, the postal charges are excessive and often prohibitive. If they are mailed under. separate covers, the delay in transmission on the catalog, or the like, which is received so long after the receipt-of the letter, will, in a great measure, cause the transaction to lose thebeneficial and psychological eflects that otherwise would obtain, by the simultaneous' receipt and consideratiton of the two pieces of mail matter.

One of the objects of the present invention is to. provide a double envelope, one for a catalog, orthe like, and the other for a letter and to indicate the distinctive character of mail matter to be contained in each em velope, on the face of one, of the composite envelopes, in a manner permissible by the postal, authorities, and convenient for the user and the persons through whose hands the dual package passes. 5

Another object is to provide an envelope that will be inexpensive to manufacture;

that will require but one address forboth. packages; one envelope provided with means for sealing, the other having an unsealed flap, to be tucked in, to retain the lower class mail matter therein.

Other, further and more specific objects If the twocommunica- Fig. 6 is a simllar view taken on line 6-6 of Fig. 1.

PATENT oraica.

In all the views the same reference char- I 'acters are employed to indicate similar parts.

. substance, in the form substantially as shown in Fig. 2, in which there arethree main sections 10, 11 and 12 that are designed to be folded upon the dotted lines 13 and 14, re-

spectively. I

Section 10 is provided at one end with a face. The first operation is to fold the section 10 on line 13 and haveit superposed above section-11, then the glued flap 17 is secured to the back or outside surface of section 10. This closes the bottom of the pocket intended for first class matter. Now, section 12 is folded over the top of section 10 and the glued side flap 18 is caused to adhere along the horizontal edge of section 11 and on its opposite or outside surface. After this has been done the flap 15 is folded over and glued to the outside surface of one end of section 12. This closes the bottom end of the pocket intended for third or fourth class matter. This leaves the glued flap 19 to close the envelope to contain first class matter after the contents is placed therein and -flap 15 having glue 16 applied to one sur I leaves the unglued, longer flap 20 open to be f ipked in after inserting the catalog, or the On the outside surface of section 12, in the upper right hand corner, the osition where the: stamp is re uired to be p aced, is printed the legend hird or fourth class postage here, or similar instruction. Near the left hand bottom corner is outlined, as at 21, the form of a first class letter, and in the right hand upper corner of'this form, in the space to be covered b the postage stamp, is rinted the legend etter postage here, Tiie stamps, therefore, for the first class matter and third or fourth class matter are placed on the same side of the double envelope. Above the space occupied by the outline 21 may be printed, for the convenience of the user, this legend Third or fourth class in this end (unsealed). An

elongated arrow 22 may point to the end referred to and within the region mentioned will be printed another legend First class in this end (sealed) with an arrow 23 pointing to the end referred to. In the section 10, instead of being laced as shown,

without changing material y the structure described.

There is no visible evidence of the third or fourth class enclosure from the front view of the structure, except that it bears stamps that are located in the upper righthand corner. The sealed flap 19 appears upon the facepresented to the observer, but the flap 20, which is tucked in around the third and fourth class matter, is not visible,

' unless the envelope be reversed, on the back side of which there is no printing or other indicia. y

Having described my invention what I claim as new and desire to secure by Letters Patent, is 2-- 1. A' double envelope made of a single sheet having three connected, rectangular sections folded on two, spaced apart, parallel lines, one end section folded over'the intermediate section, the other end section folded over the opposite folded end section and joined to the latter at its folded edge thereby to form two open pockets; an outwardly folding flap to close the respective pockets at opposite ends; a flap at each open end to be subsequently closed; a space on one side of the double structure containing directions for aflixing the stamps for the differently classified mail I matter, to be subsequently covered by the stamps to be applied; indicia on said face of the envelope indicating the character of mail matter to be contained in the respective envelopes and an outline indicating a smaller envelope with a return address within said outline and space for a mailing address therein.

2. A double pocket envelope made from a single sheet having three rectangular sections folded on two parallel lines, one end section folded upon the intermediate section and the other end section folded upon the first end section; an end flap on the intermediate section and'fol ded upon the outside of the first end section to form a pocket; at side flap on the other end section and folded upon the outside of the intermediate section to form a second pocket; two end flaps, one on the intermediate section and one on the first end section and foldable upon the outside of the second end section to separately close adjacent ends of the two pockets; and

an end flap on the second end section to close the opposite end of one pocket.

3. An envelope having two pockets for different class mail matter and made from a single sheet folded along two parallel lines to form one intermediate section and two end sections, one end section folded upon the intermediate section and secured thereto along atransverse edge by an overlying flap of the intermediate section, the other end section folded upon the first end section and carrying a flap which is folded over a longitudinal edge of the intermediate section, the intermediate and first end sections having flaps at one end of the envelope which are separately foldable in the same direction over the corresponding end of the second end section to close both pockets at one end of the envelope and the second end section having an unsealedflap that can be tucked into the open end of the adjacent pocket.

In testimony whereof I hereunto subscribe my name.

YORKE BURGESS.
